Mika Kuoppala 9d6d9f19e8 drm/i915: clean up panel fitter handling in lvds
With the previous patch "drm/i915: disable shared panel fitter for
pipe" we now disable the panel fitter at the right spot in the modeset
sequence in the crtc functions on all platforms. Hence the disabling
in intel_disable_lvds is no longer required and potentially harmful
(since the plane is still enabled at this point).

Similarly on the enabling side we enable the panel fitter in the lvds
callback only once the plane is enabled. Which is too late. Hence move
this into a new intel_pre_enable_lvds callback.

Finally we can ditch lvds_encoder->pfit_dirty - this was required to
work around the crtc helper semantics, but with the new i915 modeset
infrastructure we should enable/disable the pfit only when enabling or
disabling the entire output pipeline. So separate state tracking for
the pfit is no longer required.

[danvet: Bikeshed the commit message a bit to stress that now we
enable/disable the pfit on i9xx platforms at the right point of time
compared to the old code.]

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).

The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:

    1. The DRM provides synchronized access to the graphics hardware via
       the use of an optimized two-tiered lock.

    2. The DRM enforces the DRI security policy for access to the graphics
       hardware by only allowing authenticated X11 clients access to
       restricted regions of memory.

    3. The DRM provides a generic DMA engine, complete with multiple
       queues and the ability to detect the need for an OpenGL context
       switch.

    4. The DRM is extensible via the use of small device-specific modules
       that rely extensively on the API exported by the DRM module.


Documentation on the DRI is available from:
    http://dri.freedesktop.org/wiki/Documentation
